| Abstract: | In this paper, the principle of signal condition circuit available for Piezoelectric Accelerometers and the principle of the interfere of the circuit are described. In order to improve the application of the circuit in project, this paper presents an improved condition circuit based on high impedance op-amp TL081,which improves integrated level. Then some measurement tests were taken and the result provided that the circuit with high integrated level and low design cost is credible and feasible. |
